Specification of Letters Patent.

Patented Aug. 11 1914 Application filed July 26, 1913. Serial No. 781,419.

To all whom it may concern:

Be it known that 1, JOHN G; SMITH, a citizen of the United States, residing at VVahoo, in the'county of Saunders and State of Nebraska, have invented a new and useful Snap-Fastener, of which the following is a specification.

This invention relates to improvements in snap fasteners and more particularly to snap fasteners which include interlocking projections.

An object of the present invention is to provide a snap fastener to be used in connection with shoes, gloves, and similar articles in which two overlapping layers of ma terial are to be held in rigid and close relation.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inventio-n.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1 is a longitudinal view in section illustrating one form of my improved fastener. Fig. 2 is a view in perspective of the base member of the fastener illustrated in Fig. 1. Fig. 3 is a view in perspective of the outer securing member as illustrated in Fig. 1.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 5 and 6 represent the outer and inner layers of material which are to be held in rigid and close relation. The same may represent the overlapping edges of a glove or the upper portions of a shoe.

The inner or base member is formed with a base plate 15 provided with rearwardly struck clips 16 which after piercing the layer 6 are bent at 17 to rigidly secure the base plate thereto. It is pointed out in this connection that the cli s 16 are located adjacent one extremity o the plate 15 so as to leave the outwardly turned end 18 free for movement with respect to the layer 6. Ex-

tending from the base plate 15 is the outwardly extended curved lip 19 This lip 19 as illustrated in perspective in Fig. 2 is arcuate in cross section and the extreme end portion forms a restricted neck 20 where it connects with the base plate 15.

The outer member comprises the bent plate 21, having a curved tongue 22 which interlocks with the outturned slotted end 18 of the inner member. The bent plate 21 is rigidly secured to the layer 5 near one edge thereof by 'a rivet 23 or other securing means any desired ornamentation being used for the end face thereof. Adjacent its fastened end the curved plate 21 is provided with a slot 23 extending transversely across the plate and which, is adapted to engage the curved lip 19 and interlock therewith. From the foregoing it will be noted that the inner member is rigidly secured to the inner layer at a point removed from the edge thereof while the outer member of the fastener is secured to the outer layer at a point adjacent the free edge thereof. Thus when the snap fastener herein disclosedis used in connection with shoes, when it is desired 'to fasten or buckle the two members in their locked condition, the curved tongue 22 is first brought into interlocking engagement with the slot 11, the bent plate 21 at such time being at substantial right angles to the base plate 15. The fastened end of the bent plate 21 is then brought inward which will tend to draw the overlapping layers 5 and 6 together and bring the slot 23 into alinement with the outwardly extending curved lip19. By exerting a suitable pressure upon the said plate 21 the slot 23 is forced over the curved lip 19 which is somewhat straightened during the said insertion thereby to snap into a locked position embracing the restricted neck 20*. When it is desired to unlock or unbuckle the fastener the edge of the outer layer 5 is gripped and by moving the same laterally with respect to the layer 6, the lip and slot are first disengaged and by continuing the outward movement of the fastened end of the bent plate 21 the tongue 22 will be drawn from the slot 11 as it is thought will be readily apparent. By thus spacing the interlocking tongue and slot a considerable distance from the locking means it will be apparent that a considerable leverage action will be obtainable. Also any stress in alinement with the layers 5 and 6 will not tend to disengage the device, it being necessary that the force be exerted laterally of the layers.

Having thus described my invention, what I claim to be new and original with'me is l. The combination with overlapping layers, of a snap fastener comprising an inner and an outer member, said inner member including a base plate, means for securing the same to and remote from the edge of the 10 inner layer, the free end of said base plate provided with an outturned slotted end, the outer member including a curved plate, means for securing one end thereof to and adjacent the edge of the outer layer, the free end of said curved plate provided with an outwardly extending tongue adapted to fit within and engage the outturned slotted end of the said base plate, the fastened end of said curved plate provided with a restricted slot extending therethrough, the base plate of the inner member provided with a transversely curved outwardly extending lip and a restricted neck portion, said lip adapted to fit within and adapted to interlock with the restricted slot of the curved plate of the outer member.

2. The combination with inner and outer layers of overlapping material, of a snap fastener comprising inner and outer members, the said inner member including a base plate, rearwardly struck clips adapted to pierce the inner layer and secure the said base plate thereto, the said clips disposed at the end of the said base plate remote from the edge of the inner layer, the free end of said base plate provided with an outturned slotted end, the fastened end of said base plate provided with a transversely curved outwardly extending lip with a restricted neck portion, the outer member lncluding a curved plate, means extending therethrough turned slotted end, the other end provided with a transversely curved outwardly extending lip, and an outer member including a curved plate provided with an outwardly extending tongue adapted to fit within and engage the outturned slotted end of the aforementioned base plate and the remote end thereof provided with a restricted slot adapted to receive the transversely curved outwardly extending lip of the inner member, and means for securing the said outer member to a layer of material.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.

JOHN G. SMITH.
